Appellate jurisdiction. Regional Trial Courts shall exercise appellate jurisdiction over all cases decided by Metropolitan Trial Courts, Municipal Trial Courts, and Municipal Circuit Trial Courts in their respective territorial jurisdictions. Such cases shall be decided on the basis of the entire record of the proceedings had in the court of origin and such memoranda and/or briefs as may be submitted by the parties or required by the Regional Trial Courts. The decision of the Regional Trial Courts in such cases shall be appealable by petition for review to the Intermediate Appellate Court which may give it due course only when the petition shows prima facie that the lower court has committed an error of fact or law that will warrant a reversal or modification of the decision or judgment sought to be reviewed.
